James McVey's girlfriend Kirstie Brittain watched him cry in the jungle at a letter she wrote him – and says the ITV show has made her certain their relationship is “incredibly special”.

Emotional Kirstie has not been apart from The Vamps frontman for this long without being able to talk since they got together and he was in the jungle for their four year anniversary at the start of the month.

James is also really missing her as he was shown weeping uncontrollably when her letter was read to him in camp on Tuesday night.

Kirstie, who is waiting for him to come out at the Versace Hotel with other friends and family, told the Mirror: “I feel like I’m missing a part of me without him, as clichéd as that sounds. It’s absolutely made me realise that what we have is incredibly special.

“The first thing I’ll do when he comes out is jump on him and cry – I’ll try say I love you but it might come out as more of a sniffle or sob!”

Before going into camp, James surprised some of his fans by saying he considered sneaking an engagement ring into camp for Kristie for their jungle reunion on the camp's bridge when he leaves and said that their relationship could go to the next level in 2019.

Asked what she thought about his comments to the Mirror in a pre-show interview, model Kirstie, 23, added: “Hearing about him proposing makes me very happy as we have had endless chats about marriage, families and our future in general. I’d be more worried if he was hesitating when being asked.

“James deserves to be king of the jungle because he is such an incredibly kind and sensitive soul, immensely hard-working and wickedly funny if he is comfortable enough.

“I am super proud of him! Despite knowing he would be great, I was still terrified about him going on the show, but the experience has been hugely positive.”

Last month James also spoke bravely about diet issues and weight problems he has had in the past when he was overweight as a youngster.

In camp he has definitely lost weight but Kirstie is not overly worried. She said: “He’s definitely lost weight but I guess that’s unsurprising, he eats a LOT at home so his calorie intake will have changed massively.

“It doesn’t worry me in any real sense as he is in a very good place with food and his body right now, definitely better than in the past, so it’s more just a case of re-nourishing him when he’s out. I’m looking forward to taking him for afternoon tea.”
